Vista Del Valle is a 4,400 square feet house in the Sonoma hills that articulates modern forms, site informed design, and soft clean materials. The project is on a steep site with a view out over the valley, with distant views of Mt. Diablo and East Bay. Its multi-axis plan and gently sloped shed roofs create informal active spaces that look modern in form and yet remain soft with light finely-textured stucco and warm clear-grain horizontal cedar siding.via
